$\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3$exists as a dimmer$\left(\mathrm{A}{\mathrm{l}}_2\mathrm{C}{\mathrm{l}}_6\right)$. It is a strong Lewis acid as Al has an incomplete octet and has a tendency to gain electrons.$\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3$undergoes hydrolysis easily and forms an acidic solution.
$\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3+3{\mathrm{H}}_2\mathrm{O}\to \mathrm{A}\mathrm{l}(\mathrm{O}\mathrm{H}{)}_3+3\mathrm{H}\mathrm{C}\mathrm{l}$
i.e.,$\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3$sublimes at 100oC under vaccum.
